Inflatable Mattress Edge Support Using Segmented Reinforcing Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflatable mattresses have low support around the edges due to protrusions, leading to user falls and compromised aesthetics, which affects the user experience.
Innovation Solution
A wiredrawing inflatable mattress design featuring a wiredrawing body covered by two face layers and a side wall connected via a connecting strap composed of a fitting strap and a reinforcing strap, where the side wall overlaps with the fitting strap and is clamped between the straps, enhancing edge support and aesthetics during inflation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a chamber is left at the connection between the side wall and face layer to enable storage, then the mattress can be stored normally, but the edge support becomes low causing user falls
Solution Approach 1:
The connecting strap is divided into two functional parts: a fitting strap for basic connection and a reinforcing strap for enhanced support. This segmentation allows the strap to simultaneously provide storage capability through the fitting strap and edge support through the reinforcing strap, resolving the contradiction between storage ease and edge support reliability.
Solution Approach 2:
The connecting strap combines two different strap types with complementary functions. The fitting strap provides flexibility for storage while the reinforcing strap provides structural support for edge stability. This composite structure resolves the contradiction by integrating both storage capability and edge support in a single connecting component.
2Ease of manufacture
If the periphery of the mattress protrudes outwardly with an oval cross-section, then the mattress structure is simple to manufacture, but the aesthetics are compromised
Solution Approach 1:
The reinforcing strap is pre-positioned to cover the overlapping position between the side wall and fitting strap before final assembly. This preliminary action ensures that the connecting area is aesthetically pleasing while maintaining the simple oval cross-section structure, resolving the contradiction between manufacturing simplicity and aesthetic appearance.
3Device complexity
If the connecting strap only provides basic connection, then the device complexity is low, but the edge support is insufficient
Solution Approach 1:
The connecting strap is segmented into a fitting strap for basic connection and a reinforcing strap for enhanced support. This segmentation adds only one additional component (the reinforcing strap) while significantly improving edge support, thus resolving the contradiction between device complexity and reliability with minimal increase in complexity.

AI summary
The present application provides a wiredrawing inflatable mattress and a manufacturing method thereof. The method includes: first fixedly connecting a cut first face layer and second face layer to a reinforcing strap and trimming and forming the same, then welding the first face layer and the second face layer to two sides of a wiredrawing body respectively and trimming the same, then respectively clamping two end portions of a side wall installed with an air nozzle and an air pump between the first face layer and the reinforcing strap and between the second face layer and the reinforcing strip, performing welding and connecting successively from top to bottom, and finally, trimming the remaining edges and checking the air tightness so as to ensure the stability in use.
